Feed Water may be supplied to the eductor condenser18 througha pipe 20 coupled, in turn, to a pump 21 at the rear end of the (locomotive. The pump draws the cold Water fromlthe tender tank and delivers it into the top ofthe eductorcondenser 18.

Well as acid, and as a result there is a rapid deterioratii in of the boiler parts, as yvell as low, operating ei'iiciency.

f The gasin the feed water is eliminated by preheating the Water to a relatively hightem- I perature, saybetween 150F. and 212 F. l Within these temperatures the oxygen and gases are readily given 'ofi' trom the other Water.
